What some people do is give the new dag a new version in the name, like _v1 or _v2 at the end. Then it's treated like another dag and you can disable the old one. IF you make changes to dags, it's possible that old operators/tasks are no longer visible in the UI and you no longer have access to the log files.
Obviously, it's important to use the correct start_date in that case and probably turn off the old version.
